UNISOC head units based on UIS7862 (UMS512)/SC9863a (UIS8581A) processor - FYT platform

Actually it is iGO Pal adapted for mentioned chipset by Joying.

And, as far as I could see, the package originally came from me (was first published on this Forum). I know for sure, it’s my job.
Then then some part of arimi skin and additions from the PDA forum were added.

This means that the gentlemen from Joing did not pay for the software they distribute (again - I did pay)

I didn't have time to compare what they did/modified, and whether they did at all. Or it's just add-ons.
Apk is not a same size, whether the original, modemakias, arimi's or miochacha mods was used, takes time to analyze.
I guess they added natural support for Chinese coding

I can upload package that they send as original (without content from 2017), if anyone is interested.
